Miyuki Haruno is Miho Azuki's mother and the woman Nobuhiro Mashiro loved. She also loved Nobuhiro but could never say it and she later married someone else. She would also watch Superhero Legend with Miho when she was younger. It was only then that she realized that Nobuhiro loved her as well due to the story in Legend being based on his feeling for her. After learning of Moritaka Mashiro and Akito Takagi plan to be successful mangakas, she encourages them to go through with their dream. She once feared Miho would go down the same path as her (not confessing her feelings to the one she loves), but has been proven wrong since.
Appearance
Miyuki looks very young despite her age, even when in her fifties. She has dark gold hair that she wears in ringlets and golden eyes.
Miyuki also bears a strong resemblance to her eldest daughter Miho. When Miyuki was younger, she looked almost exactly like Miho.
Personality
When it comes to personality, Miyuki is quite similar to her eldest daughter, Miho. She had a crush on a Mashiro ever since her school days and even shared a sense of humor with Nobuhiro. However, despite her feelings for him, she grew tired of waiting for him and fell in love with another man; she still reflects on her past, though. She is very knowledgeable about who the smartest students in her children's schools are, knowing who Takagi was immediately.
Despite being kind and caring, she does have a negative trait of being too nosy about Miho and Moritaka's love life. Miyuki is good at keeping secrets unless she feels no need to keep them, but she will give hints about the secret, such as warning Miho not to go down the same path in love as she did with Nobu.
